Abstract: Objectives: This study aimed to investigate the expression of proinflammatory cytokines under long-term T helper (Th) 17 cell inducing conditions in Takayasu arteritis (TAK), a granulomatous vasculitis with adaptive immune responses. Patients and methods: This cross-sectional study was conducted between May 2014 and April 2017. Peripheral blood mononuclear cells from 25 patients (23 females, 2 males; mean age: 42.7±15.5 years; range, 20 to 69 years) with TAK and 25 healthy controls (HCs; 11 females, 14 males; mean age: 39.1±9.3 years; range, 21 to 64 years) were cultured in Th17 cell-inducing conditions for six days. Cultured cells were stained with conjugated monoclonal antibodies to determine the intracellular cytokine secretion by flow cytometry. Supernatant samples were measured with sandwich enzyme-linked immunosorbent assay for interferon-gamma (IFN-γ), interleukin (IL)-17, IL-7, IL-21, and IL-22 levels. Results: T cells and B cells was not found to be significantly different between TAK patients and HCs. No differences were observed between the subgroups of TAK according to disease activity or treatment in IL-17 and IFN-γ production. Conclusion: T cells) to IFN-γ production in TAK.
